Flew out of EWR B terminal back to Seattle today and I have to say that it's the worst airside terminal I've seen that Alaska operates out of. The food options are not great, the restaurants and terminal itself are filthy and the restrooms are small and few. Crowded, claustrophobic and dismal. It reminded me of the old SAN terminal 1 in layout, but far worse in experience.

As for the best, I'd have to go with the newly(ish) remodeled N Satellite at SEA. Spacious, light and modern with decent food options and the flagship AS lounge. I give Redmond, OR second place for best small airport experience.

I've been to most, but not all, Alaska stations. I'm curious as to other opinions from contributors to this forum...
